HENRY S. BREWINGTON, OF BALTIMORE, MARYLAND, ASSIGNOR TO NA- TIONAL CORKAND SEAL COMPANY, A CORPORATION OF MAINE.

BOTTLE-CAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 771,413, dated October4, 1904.

Application filed June 2. 1903. Serial No. 159,802. (No model.)

To (tbl whom it may concern.-

Be it known that I, HENRY S. BREWINGTON, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements in Bottle-Capping Machines, of which thefollowing is a specification.

My invention relates more particularly to a machine for placing caps onbottles and jars, and especially to that class of sealing-caps which areintended to resist internal pressure.

A further object of the invention is to provide a cheap and effectivemachine to reduce the breakage of bottles while being sealed.

The cap, to make a more perfect sealing device, should contain in thetop thereof a suitable lining or packing of paper, rubber, or cork,preferably cork, to produce the sealing results.

The machine is provided with a stationary mandrel and movable table, thetable adapted to receive and raise the bottle into position and themandrel to hold the cap thereon, while the depending flange of the capis spun or crimped under the bead on the bottle-head, thus resisting theinternal pressure of the gas in the bottle when released by the machine.The machine is so constructed that when the bottle is placed on thetable the table is raised and the bottle-head, with the cap placedthereon, is held firmly'against the mandrel. mediately subsequent to theraising of the table the edge of the cap is engaged by the spinningdisks and then released. The sealed bottle is then ready to be removedand the operation repeated. I have placed a spring under the table tocushion and take up the variation in the height of bottles. Therevolving cone, with the hinged lugs thereon, to

which are attached the spinning disks, all work automatically inperforming the function of sealing.

In the accompanying drawings, Figure 1 is a view of my improved machinein side elevation with parts in vertical section. Fig. 2 is a view infront elevation. Figs. 3 and 4 are detail views. Fig. 5 is a detail viewof the connection between the sleeve L and the gear K, and Fig. 6 is adetail showing the square shank V reciprocating in the square sleeve V Ais a T-shaped column with a base-plate B, either cast integral or boltedto it at the lower end, and there is a flange Con the upper end, whichcarries the cap-piece D. Bracket E is cast or bolted to the column nearthe lower end, which in connection with the stool F carries thepulley-shaft, which latter is provided with tight and loose pulleys atthe outer end, a bevel or miter gear G at or near the middle, 6 and aspur-pinion H at its forward end. The bevel or miter gear G drives avertical shaft I, through bevel gear-wheel Gr thereon, which through thespur-gears K and K drives the spinning sleeve L, which turns on astationary 5 but adjustable mandrel L, which is carried by the boss ofcap-piece D. The sleeve L is secured to the gear-wheel K in any suitablemanner, as by means of a key fitting in a groove in the hub L of thegear-wheel. The 7 lower end of the spinning sleeve L is provided withtwo or more lugs to which the spinning disks M M M are attached. Thesedisks revolve on arms M M, hinged to the lugs, which arms are providedon the upper end with fingers, which are pushed apart by the downwardmotion of the cone N, which is operated by the lever r and a rod 1) inthe rear of the column. As a simple means for adjusting the mandrelit-is provided with a threaded end Z, which when turned in the threadedhole in the cap-piece adjusts it up and down, and lock-nuts Z Z thereonare turned to hold it in its adjusted position.

The spur-pinionH gears into a spur-wheel 5 Q, which is fastened on ashaft S, carrying on its rear end the disk-cam R, which operates thecone N through rod 19 and lever 1', the lower end of the reciprocatingrod being slotted, as at 2, and straddling the shaft S, 9' and a stud 3,mounted on the rod and extending into a cam-groove 4, formed in the camR, whereby the rotation of the cam R causes the reciprocation of rod p,the slotted end of which serves as a guide to retain the rod inposition. On the forward end of the shaft S is a face-cam T, whichthrough roller U, carried by a hollow shoe W, raises or lowers the tableV, the shank V of which slides in a square-bored sleeve V attached tothe column A, the shank being provided with a foot 6. The foot hasloosely attached thereto the hollow shoe W, containing a spring X tomake up for different heights of bottles, as well as to have acushioning effect when they are raised and abut the stationary mandrel.The detail of cams in Fig. 4 shows how the cam T first raises the table,pressing the bottle, with the cap laid on, hard against the mandrel L.Then cam R presses the cone N down, closing the spinning wheels againstthe bottle, which is held rigidly in place by the stationary mandrel L.The wheels are revolving at a high speed, and after making about twentyturns the cam R releases the spinning wheels and bottle-cap, and thenthe cam T lowers the bottle from its raised position, so that it can beremoved.

Having described my invention, what I desire to secure by Letters Patentand claimis 1. In an automatic capping-machine, the combination with asuitable frame having a threaded aperture therein, of a threaded mandreladjustably received and held stationary within the aperture, rotatingmeans journaled on the mandrel, reciprocating means sliding upon therotary means, sealing means carried by the rotary means and actuated bythe reciprocating means, means for regulating the throw of thereciprocating means, a reciprocating support, means for automaticallyactuating the support prior to the actuation of the reciprocating meansand cushioning means carried by the reciprocating support.

2. In an automatically-operated cappingmachine, the combination with asuitable frame, a mandrel supported therein, rotating means journaled onthe mandrel, reciprocating means mounted on the rotary means, aleverconnected with the reciprocating means,

an adjustable rod secured to the lever, the lower end of the rodprovided with a slot, a driven shaft embraced by the slotted rod, a cammounted upon the driven shaft and provided with a cam-groove therein, astud carried by the rod and received in the cam-groove, a reciprocatingmeans for supporting the vertical shaft havinga gear-wheel intermeshingwith one of the gears on the vertical shaft, the drive-shaft providedwith a pinion, a counter-shaft provided with a gear meshing with thepinion, of an adjustable mandrel stationarily secured to the frame, arotating means journaled thereon, spinning means carried by,

the rotating means, a gear on the rotating means meshing w th a gear onthe vertical shaft, a reciprocating means slidingly mount ed on therotary means and operating the spinning means, a movable table and meanson the counter-shaft for actuating the table and reciprocating means atpredetermined intervals.

4. The combination with a suitable frame, a Vertical shaft having a spurand bevel gear thereon, a drive-shaft having a bevel gear intermeshedwith the bevel-pinion on the vertical shaft and provided with aspur-pinion, and a counter-shaft which has a large gear the teeth ofwhich intermesh with the teeth of the spur-pinion receiving motiontherefrom, of a mandrel, a spinning sleeve, hinged shafts carriedthereby, spinning disks carried by said spinning shafts, a spur-gear onsaid sleeve intermeshed with the spur-gear on the vertical shaft, a conemovable on the spinning sleeve and adapted to operate the spinningshafts, a movable table, and means on the countershaft for reciprocatingthe table and cone, at predetermined intervals.

In testimony whereofI have signed my name to this specification inpresenceof two witnesses.
